在使用此处地图 SDK 时膨胀异常
Inflate Exception while using here maps SDK
我正在使用此处的地图，但出现此错误：

我已遵循 SDK 用户指南。我可以将 SDK 用于具有不同应用程序 ID 的其他应用程序，但不能用于此应用程序。
这是我的 activity_map:

在logcat中可以看出错误是由于片段class处的空指针异常导致的。我该如何解决这个错误？
有时我会在 gradle 条消息中收到这些警告：

其实我觉得问题很简单：
请更改代码：
<fragment
class="com.here.android.mpa.mapping.MapFragment"
android:id="@+id/mapfragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
收件人：
<com.here.android.mpa.mapping.MapView
android:id="@+id/mapfragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
问题出在 onCreate() 我在 super.onCreate() 之前调用了初始化函数，我通过先调用 super 方法然后调用初始化方法来解决。我从没想过问题是由于这个愚蠢的错误造成的，花了 1 周的时间才找到这个！
